The newest Emergency 2012 version is already for some weeks 1.3 instead of the Steam 1.2f version.

See: http://e2012.deepsilver.com/en/downloads/patch/index.html

The patch 1.3 installation for the download version from the official game site don't work with the Steam version. When I try to install this patch the installation proces is aborted with the message InstallDir not found.
